Poly-V Roller Bearings
End caps with a multi-rib poly-V pulley profile, driven by a flat ribbed belt such as the 3PJ336. Quieter than chain and more positive than a round O-belt, poly-V is the common drive in modern carton handling.

The problem this group solves
Chain in a packing hall is loud and needs lubrication that contaminates product; poly-V gives similar grip with no oil and much less noise.
How to choose
Match the rib count on the cap to the belt — a 3-rib PJ profile takes a 3PJ belt — and set the belt length from the roller pitch.
Typical applications
- Carton and tote driven zones in packing halls
- Clean, low-noise powered roller sections
- Accumulation zones driven from a single motor roller
- Retrofits replacing chain drive to reduce noise
Where Poly V Roller Bearings is specified
E-Commerce and Parcel Handling
Zero-pressure accumulation zones built on 24 V and 48 V brushless motor rollers with poly-V slaved idlers.
SolutionZero-Pressure Accumulation Zones
Zoned accumulation built on brushless motor rollers with slaved idlers, so cartons queue without touching.
Comparison GuideChain Poly-V or O-Belt Drive Between Rollers
Once one roller in a zone is powered, the rest are slaved to it. Three drive profiles do that job, and they fail in different environments.

Frequently Asked Questions
Why poly-V instead of an O-belt?
More ribs mean more grip, so poly-V carries more drive torque than a single round belt of the same width.
How tight should a poly-V belt be?
Just enough that it does not slip under full load; over-tensioning loads the bearings and shortens their life.
